Demonstrators stand outside St Paul's Cathedral as they gather before the start of an anti-austerity protest march through central London, Saturday, Oct. 20, 2012. Tens of thousands of demonstrators are descending on the British capital to protest the government's austerity drive. Unions, anti-war campaigners, left-wing politicians, community groups and other activists hope that Saturday's march will show the unpopularity of the public sector cuts aimed at reining in Britain's budget deficit.
